Some of the world's greatest inventions were created by women. Here are three inventions that you may not know were the ideas of incredible women!

The “Board Game”

Born in Illinois in 1866, Elizabeth Magie became interested in the anti-monopolist theories of Henry George, a politician and economist who believed that a single “land value tax” would shift the tax burden to wealthy landlords. This inspired her to design a board game to teach his economic theories to friends and colleagues. Magie patented the original version of her board game “The Landlord’s Game” in 1904, which had a square pathway where players started on a corner and rolled dice to advance along spaces where they paid for properties, railroads, utilities (e.g. Water Franchise), and taxes. When landing on the fourth corner you had to follow the instructions: “No Trespassing Go to Jail”. Three decades later, Parker Brothers published a modified version, known as Monopoly. Charles Darrow claimed the idea as his own, stating that he invented the game in his basement. Magie spoke out against them and reported that she had made a mere $500 from her invention and received none of the credit for Monopoly. The relations between Magie's patents and Monopoly were discovered and subsequently, her invention of The Landlord's Game has been given more attention and she has posthumously received credit for one of the most popular board games.

Wireless Connections

Hedy Lamarr was an Austrian-born American actress (1914-2000), inventor, and film producer. She was often recognised for her major appearances in films, which led to her genius invention being ignored by society. Lamarr was always interested in the function of technology, pulling apart a music box at the age of 5. According to a new documentary on her life called ‘Bombshell: The Hedy Lamarr Story,’ LaMarr filed for frequency-hopping technology in 1941 that became a precursor to secure wi-fi, GPS, and Bluetooth now used by billions of people around the world. Her astounding achievement has her named the “Mother of Wi-Fi”, leaving a significant impact on how we use technology today.

The Fire Escape

In 1887, Anna Connelly recognised a significant issue relating to the increase of multi-leveled buildings. The number of deaths due to fires in high-rise buildings was increasing greatly. Connelly invented the fire escape, to allow people to exit the building from the exterior in the event of a fire, and for firefighters to fight the fire from the outside instead of having to go inside. She was one of the first women to submit an idea to the patent office, even before women could vote in the United States of America. This invention has saved thousands of lives for nearly 150 years worldwide.
